We modified commercially available wires for localization of non-palpable breast leasions. The modified localizing wire was used in 16 women requiring excision of non-palpable breast lesions and comparison was made with non-localizing wires. The results indicated that the modified localizing wire provided technical ease to the surgeons in removing the breast lesion and significant help to the radiolgists in placing the wire and reporting the position of the wire in relation to the breast lesion.
